A Novel Zn(Ⅱ) Complex with 4-Connected umc Topology:Synthesis, Crystal Structure and Luminescent Property

摘要

A novel complex,[Zn(L)]2·H2O (1,H2L =4-aminophthalic acid),has been hydrothermally prepared and characterized by single-crystal X-ray diffraction,IR spectroscopy,elemental analysis and PXRD.Complex 1 crystallizes in monoclinic,space group C2/c with a =12.4267(6),b =7.7482(3),c =18.6983(8) A,β =110.437(3)°,V=1687.04(13) A3,Z =4,C16H12N2O9Zn2,Mr =507.06,Dc.=1.996 g/cm3,μ =2.903 mm-1,S =0.989,F(000) =1016,the final R =0.0304 and wR =0.0720 for 12618 observed reflections (I ＞ 2o(I)).Single-crystal X-ray structural analysis reveals that compound 1 features a three-dimensional (3D) framework with 4-connected umc topology.Moreover,the thermogravimetric (TG) analysis and photoluminescent property of 1 were alsodiscussed.
